Mayer mania has finally hit the UK! Due to phenomenal demand, John Mayer will now play FOUR additional shows. Tickets for John Mayer’s first UK date sold out in rapidly, further cementing his reputation as one of Britain’s premier live draws. John Mayer finished up his short UK tour last week, which garnered impressive reviews from the dailies. Mayer returns to the U.S. next month for an extensive run of shows before coming back to Europe in May for the second leg of his European tour.
